Casting very versatile casting process has been applied to the metal and the whole machinery and electronics industries, and its use is a growing trend. Specific use, construction, hardware, equipment, construction machinery and other large machinery die casting, machine tool castings, shipbuilding, aerospace, automobiles, motorcycles, electronics, computers, electrical appliances, lighting and other industries, many of which are ordinary people all day contact, but unaware of metal objects. Advantage of using resin sand casting machine bed casting: resin sand stiffness, high initial strength which poured sand conditional use graphite cast iron solidification process of expansion, effectively eliminate shrinkage, shrinkage defects, to achieve gray iron, ductile small riser cast iron, non-riser casting. 2 solid casting used in the production of polystyrene foam pattern application furosemide feeding resin from the hard sand molding. When the liquid metal poured into the mold, foam look quickly at a high temperature gasification of liquid metal effect, burn and disappear, liquid metal takes the place occupied by the original foam, cooling solidified into the same shape and appearance of real castings. Classification mainly sand casting foundry and special casting two categories. 1 ordinary sand casting, the use of sand as a molding material, also known as sand casting, foundry, including wet sand, dry sand, and three types of chemical hardening sand mold casting, but not all sand casting can be used. Advantage of lower cost, because the use of the mold sand can be reused; drawback is time-consuming production mold, the mold itself can not be reused, must be destroyed after the finished product can be achieved. 1.1 sand (core) casting method: Wet sand type, self-hardening resin sand, water glass sand, dry and table dry, solid casting, vacuum molding. 1.2 sand core production method: is selected based on sand core size, shape, production volume and specific production conditions. In production, in general it can be divided into handmade core and core making machine. 2 special casting, press molding materials can be divided into natural mineral sand as the main form of special casting material (such as investment casting, mud casting, shell casting, vacuum casting, solid casting, ceramic casting, etc.) and metal as the main material of special casting mold (such as metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) categories.
